COMPLEXOMETRIC TITRATION IN ANALYTICAL CHEMISTRY

Complexometric titrations are a type of volumetric analysis widely used in analytical chemistry to determine the concentration of metal ions in a solution. They involve the formation of stable complexes between metal ions and a complexing agent known as a chelating agent or titrant. By adding the titrant to the analyte solution the formation of complexes is monitored using indicators or instruments such as pH meters or spectrophotometers. The equivalence point is reached when all the metal ions have formed complexes which can be detected through a sudden change in a measurable property. Complexometric titrations are particularly useful for the determination of metal ions with high precision and accuracy.
